PTFE raw material performance

Polytetrafluoroethylene (F4,PTFE) has a series of excellent performance: high temperature resistance-long-term use temperature 200~260 degrees, low temperature resistance-still soft at -100 degrees; Corrosion resistance-can withstand aqua regia and all organic solvents; Weather resistance-the best aging life in plastics; High lubrication-has the smallest friction coefficient (0.04) in plastics; Non-stickiness-has the smallest surface tension in solid materials without adhering to any substances;

PTFE fiber classification

PTFE white crimp staple fiber is generally manufactured by membrane cracking method. The fiber strength is greater than that of brown fiber produced by emulsion spinning method. The fiber can also be made into various colored fibers by pigment addition technology as required. It is suitable for high temperature environment, excellent chemical stability, low shrinkage, anti-aging and so on.

Development and Application of PTFE Material Non-stick

PTFE material has the smallest surface tension and inertness among solid materials, and does not adhere to any substances. PTFE PTFE material has the lowest coefficient of friction, excellent self-lubrication, but also has the characteristics of high and low temperature resistance, which makes it in the manufacture of non-stick pan anti-stick aspects of the application is very wide. In addition, if PTFE material is applied to rollers or other parts, used as guide wheels and polytetrafluoroethylene rollers, films, paper, textiles, etc. can pass through quickly. It can also be made into thin sheets such as chemical fiber molded sheets, textile lubricating blocks, etc. installed on looms to prevent the adhesion of various wires and PTFE special-shaped parts for mechanical equipment to prevent glue and other adhesion from being difficult to remove; as well as the use of PTFE coating and glass composite paint cloth after heat shrinkage and coated on the substrate, these applications are the use of PTFE material friction coefficient is small, non-sticky characteristics, performance of the product through the tension is reduced to the lowest, the attached dirt is also easy to clean.

Application of PTFE tube, FEP tube and PFA tube in heat exchanger

Heat exchangers are widely used in industries such as air conditioners, power plants, refineries and internal combustion engines. You may not know that you are very familiar with heat exchangers. Like the radiator in your car. The heat exchanger keeps the equipment cool and prevents overheating from causing malfunctions. You may have seen someone open the hood of a car on the side of the road and emit smoke. This is the result of a malfunction of the radiator.

FEP Features Advantages

FEP is used as film printed boards, wire and cable insulation, generator windings, electrical insulation parts (sheets, rods, tubes, frames and insulators), corrosion-resistant structural products (oil-free lubrication machine parts), coatings.. And painted glass cloth. Because of its excellent corrosion resistance, it is used in chemical work equipment, heat exchangers, fractionation towers, pumps, valves, pipes, seals, pipe linings, laboratory transparent instruments, etc. FEP extruded thin-walled tubes are used for heat exchangers, suitable for heating and cooling strong corrosive liquids in the range of -200~200 ℃
